About the Quadrilla Twist and Rail Set

Ready to shake things up? Put a twist (and shout?) into the playroom with the Quadrilla Twist and Rail set, an endlessly fascinating make-your-own marble maze.

Quadrilla marble sets consist of two basic components: blocks and rails. The colorful blocks support the rails and conduct the ball through holes, and the rails conduct the ball from block to block. Other accessory pieces add some variation: the Quadrilla Twist and Rail set, for instance, includes a five-tiered “twist” funnel, and endpieces catch the marbles at the bottom so they don’t fall on the floor and get lost under the sofa.

When kids build a Quadrilla structure, they begin to learn the basics of gravity and momentum, and once they’ve got the functions of the blocks down, they can start experimenting – what’s the tallest Quadrilla marble run they can build? How about the shortest one? The fastest? The slowest? What about adding in other building blocks? How about building a Rube Goldberg device? The more creative they are, the cooler their Quadrilla Twist structures get, and the endless possibilities lead to extended play – this is not a toy that your child will rapidly tire of.

The Quadrilla Twist and Rail set provides enough challenges to occupy both parents and kids, and for siblings to play with together, so it’s a great family activity. And you can combine it with other Quadrilla sets to build even larger, more elaborate marble mazes! Includes a funnel/helix, 32 connecting blocks, 15 accelerators, 8 rails, and 50 marbles; suitable for ages 4 and up.
